1054 | # Expect does something very strange when it receives a single braced | |
1055 | # argument. It splits it along word separators and performs substitutions. | |
1056 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
1057 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
1058 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
1059 | # "[ab]", because the backslashes will be removed by lindex. | |
1060 | ||
1061 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
1062 | # that expect will do from within TCL. And many places make use of the | |
1063 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
1064 | # of the "[func]" construct, so we need to support that too. In order to | |
1065 | # get this right we have to substitute quoted list elements differently | |
1066 | # from braced list elements. | |
1067 | ||
1068 | # We do this roughly the same way that Expect does it. We have to use two | |
1069 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
1070 | # they'll be treated as command separators, and if we escape newlines | |
1071 | # we mangle newlines inside of command blocks. This assumes that the | |

3038 | # - a regexp to use in output matching, | |
3039 | # - a value to pass to the "set prompt" command. | |
3040 | # c) It's easier to convert the plain text form to its regexp form. | |

4652 | # DEST. gdb_compile is implemented using DejaGnu's target_compile, so the type | |
4653 | # parameter and most options are passed directly to it. | |
4654 | # | |
4655 | # The type can be one of the following: | |
4656 | # | |
4657 | # - object: Compile into an object file. | |
4658 | # - executable: Compile and link into an executable. | |
4659 | # - preprocess: Preprocess the source files. | |
4660 | # - assembly: Generate assembly listing. | |
4661 | # | |
4662 | # The following options are understood and processed by gdb_compile: | |
4663 | # | |
4664 | # - shlib=so_path: Add SO_PATH to the sources, and enable some target-specific | |
4665 | # quirks to be able to use shared libraries. | |
4666 | # - shlib_load: Link with appropriate libraries to allow the test to | |
4667 | # dynamically load libraries at runtime. For example, on Linux, this adds | |
4668 | # -ldl so that the test can use dlopen. | |
4669 | # - nowarnings: Inhibit all compiler warnings. | |
968aa7ae | 4670 | # - pie: Force creation of PIE executables. |
6e8b1ab2 | 4671 | # - nopie: Prevent creation of PIE executables. |
9be5d742 SM |
4672 | # - macros: Add the required compiler flag to include macro information in |
4673 | # debug information | |
2bb8c72b | 4674 | # - text_segment=addr: Tell the linker to place the text segment at ADDR. |
f2509bee | 4675 | # - build-id: Ensure the final binary includes a build-id. |
aff9c0f8 SM |
4676 | # |
4677 | # And here are some of the not too obscure options understood by DejaGnu that | |
4678 | # influence the compilation: | |
4679 | # | |
4680 | # - additional_flags=flag: Add FLAG to the compiler flags. | |
4681 | # - libs=library: Add LIBRARY to the libraries passed to the linker. The | |
4682 | # argument can be a file, in which case it's added to the sources, or a | |
4683 | # linker flag. | |
4684 | # - ldflags=flag: Add FLAG to the linker flags. | |
4685 | # - incdir=path: Add PATH to the searched include directories. | |
4686 | # - libdir=path: Add PATH to the linker searched directories. | |
cffe02ac NCK |
4687 | # - ada, c++, f90, go, rust: Compile the file as Ada, C++, |
4688 | # Fortran 90, Go or Rust. | |
aff9c0f8 SM |
4689 | # - debug: Build with debug information. |
4690 | # - optimize: Build with optimization. | |
